Venturi-Style Electric Heater enhances air curtain capabilties.

Press Release Summary:




Employing hemispherical heating element array, 8–70 kW VTH uses Venturi effect to draw air through heating element via blower inlet before it enters discharge airstream. Discharge airstream velocity remains unobstructed in near 100% efficient heat transfer, full laminar pattern, for optimum aerodynamic performance. This creates environment-separating air seal across any open doorway while providing auxiliary heat as needed. Available voltages include 208, 240, 480, and 575 V.



Original Press Release:



Berner's VTH Electric Heater Introduction for Air Curtains is the HVAC Industry's Most Aerodynamic and Efficient



VTH Venturi-style heater and placement is up to 40-percent more aerodynamically efficient by not disrupting the air curtain's important laminar air pattern discharge.



Berner International Corp., New Castle, Pa., the nation's leading air curtain manufacturer and innovator, has introduced a patented Venturi-style heater design that offers the HVAC industry's most aerodynamic, electric heated air curtain with improved air performance efficiency by up 40-percent.



The VTH electric heater combines a hemispherical heating element array with an innovative mounting strategy at the blower inlet. The patented design uses the Venturi effect to draw air through the heating element via the blower inlet before it enters the discharge airstream. The discharge airstream velocity remains unobstructed in a near 100-percent efficient heat transfer, full laminar pattern for an optimum aerodynamic performance that creates a near perfect environment-separating air seal across any open doorway while providing auxiliary heat, as needed.



The efficiency is contrary to prior conventional air curtain industry construction where the placement of heating elements in the air discharge causes a significantly inefficient disruption of the airstream's velocity, volume and uniformity (VVU).



The VTH's innovative four-bolt mounting design is combined with quick-disconnect electrical terminals for easy maintenance or replacement accessibility within five minutes.



Complementing the hemispherical design, the VTH includes a single plane heating element array mounted entirely across the blower's opposing inlet not obstructed by the blower or motor shaft.



The VTH is available in Berner's industrial VS Series and In-Ceiling Mount Series air curtains. It comes in a range of 8kW to 70kW and voltages of 208V, 240V, 480V and 575V.  Berner also offers optional natural gas, hot water or steam coils for air curtain heating.
